Description

Built from Feb 1956 to June 1961, the 1800hp 251B-powered ALCO RS11 gave strong competition to EMD's GP-9.

Even with it's quicker acceleration and higher tractive effort, the versatile RS-11 wasn't ultimately as successful as EMD's GP-9, and as a result Conrail inherited fewer of them than their GM counterparts. Being from a defunct manufacturer, they also became candidates for earlier retirement than the geeps as well.

Four RS11's were painted CR blue: 7630, 7644, 7651 and 7652.
